Q&A with Mike Laidley, vice president of Orbital ATK’s Next Generation Launch program (members only)

A SpaceX Falcon 9 rocket lifted off from Cape Canaveral at 10:30 p.m. EDT Thursday (0230 GMT Friday). The 229-foot-tall launch vehicle delivered 60 satellites to orbit to begin the deployment of SpaceX’s Starlink Internet network, a fleet of spacecraft that may eventually number thousands.

A Vega rocket faltered minutes after liftoff from French Guiana at 9:53 p.m. EDT Wednesday (0153 GMT) and failed to reach orbit with a European-built reconnaissance satellite for the United Arab Emirates. The payload and launcher fell into the Atlantic Ocean, marking the first failure for the solid-fueled Vega launch vehicle.

Cameras mounted on United Launch Alliance’s Atlas 5 rocket show the fiery ride into space for NASA’s Mars 2020 Perseverance rover after taking off from Florida’s Space Coast.
